* Intel FSP-S configuration
Several Intel platforms require the execution of the Intel FSP (Firmware
Support Package) for initialization. The FSP consists of multiple parts, one
of which is the FSP-S (Silicon initialization phase).
This binding applies to the FSP-S for the Intel Apollo Lake SoC.
The FSP-S is available on Github [1].
For detailed information on the FSP-S parameters see the documentation in
FSP/ApolloLakeFspBinPkg/Docs [2].
The properties of this binding are all optional. If no properties are set the
values of the FSP-S are used.
